What's this? A Fiat engine clattering its way into this series, no doubt leaving splotches of oil and bits of metal on your monitors? Yes indeed, folks, back away from those Fiat stereotypes here; this engine is a true workhorse and a serious race winner as well. It was manufactured in one form or another for more than 40 years, powering everything from Fiat 124s to ungodly numbers of Lancia rally winners over the years. Thanks to Biminitwist for the tip!
